IMPROVEMENT IN HAIR-TRIGGERS FOR Fl RE-ARMS.

Specification forming part of Letters Patent No. 215,695, dated May 20,1879; applicationfiled March 6, 1879.

To all whom it may concern:

Be it known that I, EMIL ALBRECHT FERDI- NAND TOEPPERWEIN, of Boerne, inthe county of Kendall and State of Texas, have invented a new and usefulImprovement in Hair-Triggers for Fire-Arms, of which the following is aspecification.

Flgure 1 is a side view of my improved trigger, showlng the hair-triggerunset, and

parts being broken away to show the construction. Fig. 2 is the sameview as Fig. 1, but showing the hair-trigger set. Fig. 3 is a detailrear view of the same.

Similar letters of reference indicate corresponding parts.

The obJect of this invention is to furnish an improved trigger forfire-arms which shall be provided with a hair-trigger in such a way thatthe hair-trigger may be used or not, as-

A represents the hammer-shank, and B the' hammer-spring, of a gun. O isthe triggerblock, which engages with notches in the hammer-shank A whenthe hammer is cocked and half-cocked.

The trigger-block G is pivoted to the lockcase, and to its forward lowercorner is pivoted the trigger D, which passes into a slot in the saidtrigger-block O, and has its fulcrum upon the pivot of the said block 0.

The trigger D is held back in place by a spring, E, attached to theforward part of the trigger-block O, and the free end of which restsagainst the forward end of the trigger D.

F is the hair-trigger, which passes through a hole in the trigger D,enters the rear part of the slot in the trigger-block G, and is pivotedat its inner end to the rear part of the said trigger-block 0. Upon theforward side of the inner end of the hair-trigger F is formed ashoulder, to engage with a notch in the projection formed upon the rearpart of the inner end of the trigger D, as shown in Fig. 2.

The hair-trigger F is held forward, to engage with the trigger D, by aspring, D, attached to the rearwardly-projecting end of thetrigger-block O, or to the rear side of the trigger D, and the free endof which rests against the rear side of the inner part of thehairtrigger F.

, The hair-trigger F may be adjusted to any desired delicacy by means ofa set-screw, H,

which passes back through a screw-hole in the trigger D, so that thesaid hair-trigger F may strike against it, and may thus have its forwardmovement limited.

The trigger-block G is held up against the hammer-shank A by a spring,I, attached to the lock-case, as shown in Figs. 1 and 2.

The hammer being drawn back so as to cause the trigger-block O to engagethe lower notch on the hammer-shank A and hold it in position, thehair-trigger F is set by pushing the trigger D forward until theshoulder of the said hair-trigger F engages with the notch of the saidtrigger D. This forward motion of the trigger D causes the spring E,which bears against the forward end of the said trigger, to be leftunder great tension, and by pulling on the hair-trigger F until itsshoulder is released from the notch in the trigger D the spring E Willforce the trigger D backward against the pivot of the hammer-block O,the concussion of which disengages the said block from the hammer-shank.

With this construction the trigger I) may be used without any referenceto the hairtrigger F, the said hair-trigger F being only used whendesired.

Having thus described my invention, I claim as new and desire to secureby Letters Patent The combination of the hair-trigger F, and its springG and set-screw H, with the trigger D, the trigger-block G, and theirspring E, substantially as herein shown and described.
